This exchange later on, when Fighter is riding the abomination Red Mage created:
Fighter: You can ride it! Black Mage: Fighter, get down from there; you know better than to ride crimes against nature. Fighter: Aw, man. I never get to ride crimes against nature or hobos or nuthin...
Any time any character attempts to formulate a plan, there will be one of these, guaranteed. To wit:
Thief: Hm, the cannon fodder angle. I can get behind that.
Red Mage: It's certainly no good being in front of it.
After the rest of the group leaves Black Mage behind with a monster, they discuss how he's going to follow them (Fighter thinks they're going back, the rest are trying to ditch him), when suddenly BM flies through the air and lands in front of them, and gives us this.
Black Mage: I found out what zombies are weak against.
Black Mage: Killing you is going to be the greatest moment of my life.
And in the next strip, Doctor Malpractice gets stuck while trying to escape through the bathroom window as the light warriors listen from outside:
Doctor Malpractice: Darn it! I KNEW this would happen. I'm FAR too big. I need some help in here, but who would want to actually DO that?! Dammit, I thought elves were supposed to be scrawny twig boys! Argh! Now I'm all tangled up in my robes! I hope I can get un-tangled before I make a mess of things. If I wasn't so big, this wouldn't be a problem.
From the invasion of Dwarfland arc:
Thief: Ack! Beard-shaped parasites are eating their faces!
Dwarf: By Moradin's beard! Why do only our homes and children burn?!
BM (winking): Because it seemed excessively cruel!
Dwarf: Everything I love is combustible!
Dwarf: Why aren't I dead yet?
Vilbert von Vampire, the LAR Per. The Light Warriors have to go along with his arbitrary set of rules to fight him. Hilarity Ensues when it dawns on Fighter that he's...well, a vampire. So he goes to get an appropriate weapon...
Fighter: (swinging a chunk of a fence with a cow on it) COWBONG! (Clobbers Vilbert)
Black Mage: A WOODEN STAKE!
Fighter: I know; what do you think the fence post is for? I'm not stupid.
Black Mage: That's not a stake.
Fighter: Well, no, not yet. (turns Black Mage around to shoot fire at the down Vilbert and Cow on a stick) Now it's Wood in Steak.
Red Mage notes how Black Mage has finally lost it from constant exposure to Fighter...
Black Mage: (staring at the fire) Wooden Stake. Wood in Steak...
Even better when you're aware that except for the "uh...", it's a verbatim quote from the English translation of the first Final Fantasy game.
The "stuck on an island" arc. All of Red Mage's attempts at chocobo transportation/genetic engineering/surgery.
Red Mage (after creating a horribly mutated chocobo): All it required was a cocktail of dangerous experimental surgery and a willingness to ignore the unnecessary suffering of perfectly innocent beings! Also, I shot magic into their chromosomes until they turned inside-out. Evolution is my bitch.
The icing on the cake was Black Mage's Eye Take and awkward glancing back and forth, just TRYING to think of what the hell to say.
Red Mage: Behold the fruits of genius!
[Cut to the horrific chocobo]
Black Mage: [after aforementioned Eye Take and awkward glancing] What is it?!
Red Mage: We went over this. Fruits of genius.
A short time before the above entry, Black Mage's repeated assaults on Fighter's cranium start having an effect:
Thief: Looks like that stab to the head wasn't so bad after all.
Red Mage: Fighter! (holds out index card) Do as the card commands! (Beat Panel) Red Mage: ...Fighter? Fighter: It hasn't said anything yet... Black Mage: Take the card and then read the card. Fighter: (does so) 'Kay. (BZZZRR!) Red Mage: Should have probably told Black Mage to get out of the way. (Black Mage gets back to his feet) Black Mage: WHAT. DID YOU WRITE. ON THAT CARD.
Red Mage freezing the team to keep them from being killed by the Ice Dragon? Funny. Expecting Black Mage to come and thaw them out with one of his many fire spells? Funny in a very pitiable way. Black Mage dropping out of his current fiery rampage to stare at the now frozen Light Warriors for two panels before going far in the background to deliberately squander more fire spells at everything but the ice block? Priceless.
A meta-example. Clevinger is best known as a Teasing Creator, and he created a fake, anticlimactic ending, expecting to receive tons of hate mail. Instead he was flooded with mail about how appropriate the ending was and had people thanking him.
*KABOOM* "Yar? ...Must be Explodin' Tuesday." and ''"WHY WOULD IT EXPLODE?"'
Red Mage: So deep are we (within my A-hole) that Sarda will never find us no matter how thoroughly or how vigorously he probes my A-hole. Black Mage: Can you say things without talking? Is that...Can we do that? Please? Red Mage: What's wrong? All I'm saying is that we're deep, deep in my A-hole. Black Mage: Stop using that word! Red Mage: O...kay. Black Mage: Thank you. Red Mage: Would you prefer to say that we are in my B-holenote can be construed as "bunghole" or "butthole" then? Either is accurate. Black Mage: I'm...not sure what that could refer to, and it makes me worried.
Red Mage: I can fix all of this. Black Mage: Ohhh, no you don't. If I have to listen to one more of your word salads in the guise of a plan, I will kill myself so hard it will kill you instead. Red Mage: No, no, no. This is so stupid it's completely foolproof. Black Mage: That's not how stupid works! There's a critical mass of stupidity beyond which no additional amount of stupid will improve your chances for success!
Red Mage: Oh, the dreaded goblin punch! Thief: You call it a goblin punch. Even though it was very clearly a kick. And their isn't a goblin within a thousand mile radius. Red Mage: What? That's the name of the move as chronicled by the greatest cryptozoologist in red mage history: Blindy O'Sightless. Thief: The more I learn about you, the more it makes sense. Red Mage: That's a good thing, right?
In the very next comic, Black Mage puts his newly learned...er, "Goblin Punch" to great effect.
Black Mage: (running as fast as he can) INNA NERTS! (Mushroom cloud explosion panel, indicating that Black Mage has kicked the target into orbit)
Red Mage: Maybe we're trying too hard. Thief: We've never done that and you goddamn know it.
"QUEST COMPLETE!", and this...
Red Mage: Well, yeah. But I mean, maybe we can't make our own quests. We have to find them out there in the world. Roaming free, pure, beautiful. * Beat Panel, as Black Mage and Thief share a weird look* Black Mage: That got a little weird at the end.
The expression on the guy's face in the third panel of this strip, combined with this gem from Black Mage:
Fighter managing to make several 'bear' jokes one after the other, successfully pissing off Black Mage.
Soon after, Thief dismisses the supposed hauntedness of the woods they're in:
Thief: We're not too worried, thanks. I'd like to think I know my way around a forest. Y'know, since the essence of my being resonates with the very concept of "forest." And frankly, I've seen darker wood in elf porn. (Black Mage immediately throws up.) Ranger: Your elf eyes do see the living forest itself, that much is clear to me. But there is much more that you cannot see. Black Mage: Man, and I didn't lose it when I caught a glimpse of an elder god defecating. Fighter: (looking down) You got it on my shoes. Black Mage: It shat out advertising executives. They're the bowel obstruction that killed the old universe.
The second nightmare Black Mage has due to the poisoned cookies Matoya gives the Light Warriors. Absolutely hilarious.
White Mage says that she doesn't know whether the Light Warriors are alive or not. Cue this.
Black Mage taking out the Nintendo Power issue in here which he had already taking out here. It also counts as a Crowning Moment Of Awesome for being the longest set up in a webcomic, lasting 9 years and 1214 strips.
The Light Warriors are about to face Sarda while he is "charging" the power of the Orbs into himself. Black Mage and Thief run away, taking Fighter with them, leaving Red Mage alone with Sarda. RM says that this is quite normal, and Sarda replies "Preaching to the choir." Red Mage asks if Sarda is sympathic to his plight. CueEvil Laugh.
It shoots fire from its mouth and bleeds acidic lava! Run for your pathetic lives! Use your weapons, they are designed to inflict damage! Our weapons are useless, reliance upon them is death! It has exposed its weak, fleshy underbelly to me in the form of its digestive tract!
Black Mage: Does that LOOK like an invisible sky castle? Fighter: Sure, maybe. I've never seen one. —>Black Mage: Can you imagine why? Fighter: ... Fighter: ... Fighter: Because they're quite rare? Thief:Technically he's not wrong, you know. Black Mage: But he SHOULD be.
